Polyethylene terephthalate (PET) microplastic particles in water: EURM®-060
EURM®-060 is a reference material (RM) that, upon reconstitution, provides polyethylene terephthalate (PET) microplastic particles in a water matrix. It was produced in accordance with ISO 17034:2016 and ISO 33405:2024.
EURM-060 contains microparticles made from pristine PET polymer; PET was selected due to its common application for plastic bottles, commonly used for drinking water. Pristine PET was purchased as a powder with an upper particle size of 300 µm. The material was milled and the particles (with an equivalent diameter smaller than 50 µm size) were partly removed by sonicated wet-sieving. The RM is available as a set consisting of one 10 mL amber glass vial with PET particles embedded in a freeze-dried NaCl carrier, one glass bottle containing 950 mL of deionised water and one amber glass bottle containing 60 mL of 0.1 % Triton X-100 surfactant solution.
Between-unit homogeneity was quantified and stability during transport and storage was assessed in accordance with ISO 33405:2024. The homogeneity and stability were assessed towards both the mass concentration and the number concentration of the PET particles dispersed in water.
Uncertainties related to homogeneity and stability were estimated in accordance with ISO 17034:2016 and ISO 33405:2024.
The material is intended for quality control and assessment of method performance.
